Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509876, here are decompositions:

13 + 509863 = 509876
43 + 509833 = 509876
79 + 509797 = 509876
109 + 509767 = 509876
139 + 509737 = 509876
223 + 509653 = 509876
229 + 509647 = 509876
307 + 509569 = 509876

Showing the first eight; more decompositions exist.
